A cohort study was conducted to examine the association of an increased body mass index (BMI) with late adverse outcomes after a carotid endarterectomy (CEA). It comprised 1597 CEAs, performed in 1533 patients at the Vascular Surgery Clinic in Belgrade, from 1 January 2012 to 31 December 2017. The follow-up lasted four years after CEA. Data for late myocardial infarction and stroke were available for 1223 CEAs, data for death for 1305 CEAs, and data for restenosis for 1162 CEAs. Logistic and Cox regressions were used in the analysis. The CEAs in patients who were overweight and obese were separately compared with the CEAs in patients with a normal weight. Out of 1223 CEAs, 413 (33.8%) were performed in patients with a normal weight, 583 (47.7%) in patients who were overweight, and 220 (18.0%) in patients who were obese. According to the logistic regression analysis, the compared groups did not significantly differ in the frequency of myocardial infarction, stroke, and death, as late major adverse outcomes (MAOs), or in the frequency of restenosis. According to the Cox and logistic regression analyses, BMI was neither a predictor for late MAOs, analyzed separately or all together, nor for restenosis. In conclusion, being overweight and being obese were not related to the occurrence of late adverse outcomes after a carotid endarterectomy. © 2023 by the authors.

Since its outbreak, coronavirus disease 2019 (COVID‐19) has rapidly spread throughout the world. The Serbian government declared a state of emergency on 15 March, 2020, implementing some of Europe’s strictest measures to combat the pandemic. The aim of this study was to determine the impact of the COVID‐19 epidemic on the mental health of the general adult Serbian population and to identify associated factors during the state of emergency and lockdown. Data were collected with a snowball sampling method between 23 March and 25 April, 2020, by using an online questionnaire. Multiple ordinal regression was performed to establish the associations between socio‐demographic characteristics, self‐estimated health status, and depression, anxiety, and stress. Out of 1057 participants included in the study, 28.9%, 36.9%, and 38.1% reported moderate to severe depression, anxiety, and stress symptoms. Uneasiness related to COVID‐19 news, the feeling of helplessness, likeliness of impending death, and presence of COVID‐19 symptoms were associated with higher depression, anxiety, and stress scores. Current smoking status was associated with a higher risk of depression and stress. Students had a significantly higher level of depression and stress, while older age was protective against anxiety and stress. Higher socioeconomic status was significantly associated with lower levels of depression, anxiety, and stress. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.

Onychomycosis is a fungal infection of the fingernails and/or toenails caused by dermatophytes, yeasts and non-dermatophyte moulds. The epidemiology of onychomycosis in Serbia is yet to be fully established. This epidemiological study was aimed at evaluating the epidemiology of onychomycosis in a sample of the Serbian patients at risk of onychomycosis, to determine the fungal aetiological agents and to identify the possible risk factors. The study population included 374 patients from six centres in Serbia with suspected onychomycosis. Demographic data, data about comorbidities, lifestyle, clinical aspects of onychomycosis, trauma, excessive perspiration and personal and family history of previous onychomycosis were studied. Laboratory confirmation of diagnosis was done by direct microscopy, fungal culture and PCR. Diagnosis of onychomycosis was confirmed in 50.8% of patients, who tested positive to at least one laboratory test (direct microscopy, fungal culture or PCR). Trichophyton rubrum was predominant both on toenails (85.98%) and on fingernails (38.46%). Independent risk factors for onychomycosis were: old age (OR = 2.285; P < 0.001), family history of previous onychomycosis and/or tinea pedis (OR = 2.452; P = 0.005), excessive perspiration (OR = 2.165; P = 0.002) and higher degree of hyperkeratosis (OR = 1.755; P = 0.020). This is a first epidemiological study of onychomycosis from Serbia. © 2016 Blackwell Verlag GmbH

Influenza is a major cause of morbidity and mortality worldwide, but is vaccine preventable. It is important to know the knowledge, attitudes and practices of medical students regarding influenza vaccination since these may influence their practice of medicine in the future. Therefore, in this study we aimed to determine the knowledge, attitudes and practices of Serbian medical students at the Faculty of Medicine, Belgrade, Serbia in order to inform the education curriculum at the study institution. This study was conducted during 5-23 December 2011. Study subjects were all fourth year medical students who were willing to participate in the study. Each student was asked to complete a self-administered anonymous questionnaire asking about their knowledge, attitudes and practices regarding influenza vaccination. A total of 413 subjects were included in the study (response rate of 83.6%). The mean [± standard deviation (SD)] age of study subjects was 22.7 (± 1.6) years; 63.9% females. Fourteen percent of subjects had previously received a vaccine to prevent against seasonal influenza and 4.8% had previously received a vaccine to prevent against pandemic influenza. Self-protection was the most commonly given reason for receiving influenza vaccination. Lack of time, forgetting to get the vaccine, not realizing their risk and belief the vaccine was ineffective were the main reasons for not receiving influenza vaccination. On multivariate regression analysis, belief that all medical students should be vaccinated against influenza [Odds Ratio (OR) = 2.93; 95% Confidence Interval (CI): 1.36-6.30] and receipt of pandemic influenza vaccine (OR = 16.74; 95%CI: 5.59-50.11) were factors significantly independently associated with receiving the seasonal influenza vaccine while receipt of annual seasonal influenza vaccination was significantly independently associated with receiving the pandemic influenza vaccination. To summarize, the percentage of subjects who had received influenza vaccination was low. In conclusion, subjects at the study institution need to be educated about their risk for contracting influenza and the efficacy of the vaccine. Receipt of the vaccine should be made more convenient so as not to take a long time to receive it and a vaccine should include coverage of both the pandemic strain and the seasonal strains in order to improve study subject uptake. © 2019, SEAMEO TROPMED Network.

Background/Aim: Prehypertension and hypertension are an important public health problem worldwide and although they can be modified, they are often a risk for cardiovascular diseases. The aim of this study was to determine the prevalence of prehypertension and hypertension and associated risk factors in the adult population (15+ years) of Serbia. Methods: The cross-sectional study covered 14,623 adult respondents, but 14,422 volunteered to measure their blood pressure according to a pre-defined protocol. A stratified two-stage national representative random sampling approach was used for the selection of the survey sample. Results: In 2013, 17.7% of Serbian population, aged 15 and over, was normotensive, every third (33.1%) person had prehypertension, and every second (49.3%) had hypertension. The standardized prevalence of prehypertension and hypertension was 40.6% and 34.5%, respectively; 57.8% of the hypertensive population were receiving medical treatment. Among those receiving medical treatment, 35.2% (36.4% males and 33.2% females) had a blood pressure within the normal range. According to the results of multivariate logistic regression analysis, independently significant risk factors for hypertension compared to persons with normotension were older age (50 and more) (p < 0.001), overweight (p < 0.001) and obesity (p < 0.001), moderate (p < 0.001) and large (p < 0.001) waist circumference in both sexes, and nonurban place of residence in females (p = 0.006). In females, independently significant risk factors for prehypertension compared to persons with normotension were older age (50 and more) (p < 0.001), overweight (p < 0.001) and obesity (p < 0.001), moderate (p < 0.001) and large (p < 0.001) waist circumference, but high level of physical activity was significantly protective (p = 0.014). In males, overweight (p < 0.001) and obesity (p < 0.001) were independently significant risk factors for prehypertension. Conclusion: Serbia belongs to countries with a high prevalence of prehypertension and hypertension. Our results emphasize the need for a new public health strategy for the prevention, detection and treatment of prehypertension and hypertension. © 2020 Inst. Sci. inf., Univ. Defence in Belgrade.

Objectives: Medical students represent a group particularly at risk of involuntary childlessness due to their highly demanding careers and university curriculum. The aim of this study was to investigate Serbian medical students’ attitudes towards future parenthood and their awareness of fertility issues. Methods: A cross-sectional study was conducted among fourth year students at the Faculty of Medicine, University of Belgrade, Serbia, between 12 and 16 December 2016. Data were collected through an anonymous 56-item validated questionnaire, translated into the Serbian language. The participation rate was 87.1%. Results: More than 95% of students, regardless of gender, wanted to have children in the future; most indicated three as the desired number of children. Both genders equally rated the importance of having children. Women rated significantly higher the likelihood of IVF treatment or child adoption if faced with infertility (both p =.001). All students wanted to have their first child before the age of 35 years. Knowledge about the age-related decline in female fertility was not satisfactory. Women found it more important to have children when they felt sufficiently mature, were in a stable relationship, were financially secure, had completed their studies, were not too old to have children, and had access to childcare, although these prerequisites were rated highly by both genders. Conclusion: Serbian medical students greatly value and have a positive perception of future parenthood. Appropriate education is needed, however, because of their inadequate knowledge of the age-related decline in female fertility. © 2017 The European Society of Contraception and Reproductive Health.
